ELP-362M Underwater Locator Beacon 1


1 Description

The ELP-362M and ELP-362M90 Underwater Locator Beacons are durable, water-activated, underwater location aids. The beacons transmit an acoustic signal at 37.5 kHz once every second after activation. The acoustic output for the 30 day battery will remain above 157.0 dB for 30 days. The acoustic output for the 90 day battery will remain above 157.0 dB for 90 days. The ELP-362M90 Underwater Locator Beacon with 90 day battery life meets the AS8045a Specifications and can be used on all new Voyage Data Recorders manufactured after July 1, 2014. The ELP-362M Underwater Locator Beacon with 30 day battery life can be used on all Voyage Data Recorders manufactured prior to July 1, 2014. RJE International, Inc. also offers both a standard mounting bracket kit (P/N B362-05591) and a customer specific mounting bracket kit (P/N B362-08320). Either kit allows the beacon to be securely mounted (Please contact RJE International, Inc. if the standard mounting bracket does not meet your needs). The beacon and its standard mounting bracket are shown in Figure1-1. The beacon is also shown installed in its standard mounting bracket in Figure 1-2, and a dimensional outline of the beacon is shown in Figure 1-3.

This section provides a general descriptive overview of the beacon, its theory of operation, and use.

Figure 1-1 ELP-362M90 and Mounting Bracket



Figure 1-2 ELP-362M90 Installed in Mounting Bracket

External Construction

The beacon is contained in a water-tight aluminum case capable of withstanding high-impact shock and deep-water immersion. As shown in Figure 1-2, one of the end caps has a water-activated built in switch that causes the beacon to begin transmitting when the switch comes in contact with water.

Figure 1-3 ELP-362M90 Dimensions



Internal Construction

The major internal components of the beacon include a printed circuit board assembly, a urethane-encapsulated transducer assembly, and a battery. The battery is contained in its own, separate, user accessible compartment.

Theory of Operation

The printed circuit board assembly generates all the necessary logic functions to produce a pulse with the desired characteristics. The pulse is then transformed from a CMOS level square wave to a much larger 37.5 kHz sinusoidal pulse by a transformer. The output of the transformer drives the urethane-encapsulated transducer, which propagates through the housing in the form of a tuned 37.5 kHz acoustic signal.

Locating the Beacon

When the beacon is immersed in water, it will begin to radiate an acoustic signal which can be received and transformed into an audible signal by either the RJE International, Inc. APR-272 or DPL-275A Acoustic Pinger Receivers. When used in conjunction with the RJE International, Inc. Model DHA-151 Directional Hydrophone, either pinger receiver can be used as a shipboard portable receiver to determine the general vicinity of the VDR Capsule. After the area is known, a diver can be deployed with the DPL-275A, which will give the exact location of the VDR Capsule. Other equivalent pinger receivers may also be used.

3 Installation and Checkout

This section encompasses the installation considerations and procedures for mounting the beacon using the mounting bracket kit, and a pre-deployment test that can be conducted using a RJE International, Inc. ATS-260M Acoustic Test set.

Installation Considerations

To minimize the probability of physical damage or inadvertent activation, the following precautions should be considered when mounting the beacon:

The beacon should normally be mounted in according to the recorders manufacturer recommendations and should be mounted to a sturdy structure without weakening the structure itself.

The beacon should be mounted in an area guarded against heavy equipment tearing loose and striking the beacon and should be mounted in a way that provides convenient access during regular inspections and tests.

The beacon should be mounted in an area where sound absorbent materials are not present. Avoid affixing labels to the beacon or any other material that would affect the acoustic beam.

The shelf life of the battery will be decreased when exposure to higher than normal temperatures. The maximum temperature where the beacon

is mounted should not exceed 71ºC (160º F).

Nonconformance to the mounting instructions or intended use may void the warranty.



Installation Procedures

Carefully unpack the beacon and inspect it for shipping damage. If any damage is evident, it should be reported to the freight carrier and to RJE International, Inc. The mounting bracket kit includes an aluminum mounting bracket, an aluminum end plate, three drilled (for lockwire) socket head cap screws, and three lock washers.

NOTE: Before installing the mounting bracket, be sure that it will be

possible to install and remove the beacon once the bracket is installed.

To mount the beacon, perform the following steps:

1. Refer to the mounting bracket hole pattern shown in Figure 3-1 and drill four 0.191 in (0.48 cm) diameter holes.

2. Secure the mounting bracket with four 10-32 stainless steel screws and

associated hardware (not supplied) as shown in Figure 3-2.

3. Slide the beacon into the bracket as shown in Figure 3-3. Rotate the beacon until the battery date is visible and secure it in place with the end plate and the three drilled socket head cap screws.

4. Lockwire the drilled screws and clean the water activation switch (refer to section

4 Beacon Cleaning).

Pre-Deployment Tests

A pre-deployment test on each beacon should be performed before and after mounting using the RJE International, Inc. ATS-260M Acoustic Test Set. The test set can be used to check both the beacon’s battery condition and operation. Also, an alternative method using a digital voltmeter can be used to check the beacon’s battery condition.

ATS-260M Acoustic Test Set

To use the ATS-260M Acoustic Test Set to verify the battery condition and test the operations of the beacon, use the following procedure:

1. Place the test set probe on the water activation switch as shown in Figure 3-4. It is not necessary to remove the beacon from the mount to conduct the test.

2. Place the hand probe on the exposed stainless steel contact on the other end of the beacon, as shown in Figure 3-4. Do not place hand probe on anodized surface.

3. Hold down the button labeled PUSH TO TEST on the test set handle.

4. Check the beacon battery condition by observing the green and red indicators on the test set.

If the green indicator is lit, the battery is good.

If the red indicator is lit, the battery should be replaced. (See Section 3 Alternate Battery Check)

5. Check the beacon operating condition by listening for an audible tone from the test set and /or observing the amber indicator.

If there is an audible tone and /or the amber indicator is flashing, the beacon is operating properly.

If there is no audible tone and the amber indicator is not flashing, the beacon is not operating properly.

NOTE: If the beacon does not operate properly, return it RJE International,

Inc. for service. (See Section 5 Return Procedures for instructions on how to return the beacon.)

ATS-260M Acoustic Test Set Service

The ATS-260M Acoustic Test Set is factory calibrated at the date of manufacture. Under normal operating conditions the tester does not require re-calibration; however, should service be required, contact RJE International, Inc. (See Section 5 Return Procedures for instructions on how to return the test set.)



Alternative Battery Check

In addition to using the test set to check the beacon’s battery condition, a high-impedance (minimum input impedance of 10 Megohms) digital voltmeter can be used to measure the battery voltage. Use the following procedure to measure the battery voltage:

1. Place the negative meter lead on the water activation switch.

2. Place the positive meter lead on the exposed stainless steel contact on the beacons other end. Do not place the meter lead on anodized surface.

3. Read the voltmeter.

If the voltmeter reading is 6.0 volts or more, the beacon has sufficient operating power. If the voltmeter reading is less that 6.0 volts, DO NOT remove the battery access end cap. (See Section 5 Return Procedures for instructions on how to return the beacon.)

WARNING: Failure to observe these precautions could result in the release

of hazardous chemicals.



4 Beacon Maintenance This section covers the cleaning, recommended testing interval, disposal, storage procedures, and battery replacement for the ELP-362M and ELP-362M90 Underwater Locator Beacons.

Beacon Cleaning

The end cap with the water switch and the end cap with the exposed stainless

steel contact, should remain free and clear of dirt, grease, and dust. The end caps should be cleaned with a mild detergent and dried thoroughly with a clean cloth. This process should be repeated periodically depending on the local environment.

Periodic Beacon Test

When the beacon is installed on a voyage data recorder, the recommended

maintenance interval is the same as that of the recorder, or 12 months, whichever is shortest. Follow the Pre-Deployment Tests referenced in Section 3 of this User’s Manual.

Beacon Maintenance Precautions

The following precautions should be exercised when handling or storing the

beacon:

The beacon should not be exposed to temperatures in excess of 71ºC (160ºF), as the battery life can be reduced by storage in a high temperature environment.

Any situation that could possibly crush or penetrate the case of the

beacon should be avoided.



Battery Maintenance
